Hello,
I recently came across a good resource book to share with members of the forum. It is called "Old Outboard Motor" service manual volume 1. The publisher is Intertec and it covers motors below 30 hp prior to 1969. I found it through my local library.
In the section devoted to Evinrude and Johnson, 7.5 an 10 hp from the years 1955 to 1963 the fuel/oil ratio is as follows;
7.5 Evinrude and Johnson, 16:1, 1/2 pint to a galllon of unleaded gasoline
10 Evinrude and Johnson, 24:1, 1/3 pint to a gallon of unleaded gasoline.
This information was found on page 184 of this manual.
I don't own an owner's manual for my 7.5 hp Johnson[1958] but if someone out there does perhaps they could verify or dispute the information I have found.
I really enjoy reading the forums and would appreciate any feedback with respect to the above topic.
Thanks so much.
SPK.
